| upper bounds value from the <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Nodes.TermRangeQueryNode.html">TermRangeQueryNode</a> object and try |
| to parse their values using a <code>dateFormat</code>. If the values cannot be |
| parsed to a date value, it will only create the <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Nodes.TermRangeQueryNode.html">TermRangeQueryNode</a> |
| using the non-parsed values. |

| <section><p>The <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Parser.StandardSyntaxParser.html">StandardSyntaxParser</a> creates <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Nodes.PrefixWildcardQueryNode.html">PrefixWildcardQueryNode</a> nodes which |
| have values containing the prefixed wildcard. However, Lucene |
| <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Search.PrefixQuery.html">PrefixQuery</a> cannot contain the prefixed wildcard. So, this processor |
| basically removed the prefixed wildcard from the |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Nodes.PrefixWildcardQueryNode.html">PrefixWildcardQueryNode</a> value.</p> |
